Mining presents one of the harshest environments of any industry. This applies to equipment and assets and the concrete structures that are essential for mining establishments to function. While the use of coatings on the mechanical elements of an operation is widely accepted, utilising similar advanced protection on concrete surfaces can also dramatically impact the bottom line of a mining, mineral and ore processing plant.
Concrete: The Challenges
Concrete is a hardwearing substance, but mining demands put this widely used material under immense pressure. From excessive weight-bearing to chemical and abrasive attacks, without additional protection, the lifespan of concrete is shortened by tough 24/7 use.
Enter concrete coating – a simple reinforcement method that has multiple advantages:
- Prevents mechanical wear and abrasion that damages the integrity of the surface
- Effectively prevents the migration of water or reactive chemical compounds into the concrete
- Can restore damaged structural supports, including column supports, tank pads, beams, and pump bases
- Enhances safety, reducing trip and fall hazards
- Reduces the frequency of fork truckload spills
- Reduces the likelihood of environmental fines
- Makes washdowns and cleaning easier
- Improves the aesthetics of the site
The remote nature of the mining and resources sector means it’s essential that repairs and refurbs are kept to a minimum. Therefore, concrete flooring solutions must be hardwearing, long-lasting and easy to maintain.
Advanced Concrete Coating Choices
The choice of concrete coating is crucial. Get it right, and longevity can be increased by years – even in plant areas regularly exposed to concentrated chemicals, such as acid, alkalis and solvents.
A quartz reinforced concrete resurfacer that’s been designed specifically to stand up to such harsh conditions can have remarkable results. The Chesterton ARC 988 is a world-leading choice that can be used to replace acid-resistant tiles or phenolic, furan or polyester successfully. Once in place, it resists cracking and delamination, leading to a dramatically extended lifespan of the surface. Easy to apply by trowel, it can be used to coat new concrete surfaces and existing ones that have already undergone severe degradation, either from chemical or physical damage.
Other concrete repair choices include the Chesterton ARC EG-1 that can be quickly applied to voids of up to 30 cms (12 inches) and then coated with other ARC coatings to improve longevity further. ARC EG-1 is also suitable for building up low areas, forming curbs and pads, and creating slopes to drains.
ARC EG-1 is an epoxy grout that offers multiple advantages:
- Low viscosity, moisture tolerant amine cured epoxy reinforced with a blend of dried and graded silica aggregates
- 100% solids
- Zero VOCs
- Flowable for deep pour application
- Adheres to dry or damp concrete
- Can be manually applied up to 30 cms (12 inches) deep in a single coat
- Ready for top coating within 6-8 hours and foot traffic in 16 hours.
